DIE FOR FORMING FENCE-TIES.

SPECIFICATION forming part of Letters Patent No. 778,844, dated January 3, 1905.

Application filed April 28,1904. Serial No. 205,374.

To all whom it may concern:

residing at Adrian, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Dies for Forming Fence-Ties; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which we have contemplated embodying our invention, and said invention is fully disclosed in the following description and claims. 7

Referring to the drawings, Figure 1 represents the two members of the die in operation in connection with a staple and a plunger for inserting the latter. Fig. 2 represents a plan view of the lower die member, showing the cross-wires and the completed tie in positions which they occupy after the tie is completely formed. Fig. 3 is a plan view of the lower die member. Fig. 4 is a plan view of the upper die member inverted. Figs. 5 and 6 are vertical central sections of the complete die, taken longitudinally and transversely, respectively. Fig. 7 is a detail View showing the cross-wires and a staple in the position in which it enters the die. Figs. 8 and 9 are similar views showing successive stages in the formation of the tie. Fig. 10 is a detail of the cross-wires, showing the kinks produced by the die, the tie being illustrated in dotted lines in this figure.

The object of our invention is to provide a die for forming a fence-tie of peculiar construction, attaching it to crossed wires of a fencing or similar wire fabric, and simultane-.

ously forming interlocking kinks in the crosswires.

The novel form of fence-tie herein shown and described is not claimed herein, as the same will form the subject-matter of a separate application for Letters Patent. This improved fence-tie is formed from a staple such as is illustrated at S, having the bend or curved portion 8 and legs .9 s of equal length, and which is straddled diagonally across the intersecting portions of two diametrically-disposed wires, as A and B. (See Fig. 7.) The staple or tie blank is then driven or forced into the die, hereinafter described, which bends the legs of the staple in opposite directions around the same wire, as A, and forces the ends of the legs beneath the bend s of the staple between said bend and the other wire, B, as is illustrated in Figs. 8 and 9.

Our present invention consists in the peculiar construction of die hereinafter described.

The die comprises two coinciding die members C and D, which are preferably held by suitable means, either singly or in groups, in a machine. The lower die member D is provided with a wire-holding groove d, extending across the upper face of the same, said groove being of greater depth adjacent to its ends and the bottom of the groove being thereby provided with a hump or projection centrally where it forms the bottom of a short transversely-disposed oval recess d. On each side of the wire-holding groove d (which is designed to receive one of the cross-wires, as B) is a recess (Z parallel to the wire-recess cl and having acurved bottom to receive the ends of the staple and bend them in the manner indicated in Fig. 8. The die member D is also provided with supplemental re cesses d" (Z located on opposite sides of the central wire-holding recess cl and disposed diagonally with respect to the center of the die for receiving the ends of the staple-legs after they have been bent and forced beneath the bend s of the staple and bending said ends inwardly as the staple is completed. The upper die member 0 has its lower face provided with a wire-holding recess 0, extending across the same in such a manner as to lie at the desired angle to the wire-recess (Z as to hold the wires A and B in the relative positions desired. In the present instances the wire-recesses c and d are disposed perpendicularly with respect to each other, and the recess 0 holds the wire A in position, as indicated in Fig. l. The die member G is also provided with two parallel recesses 0 c, disposed angularly to the recess 0 and in such manner that the said recesses 0 0 will engage the ends of the staple after they have been bent inwardly by the recesses (Z (Z and further bend them diagonally across the intersection of the wires A and B beneath the bend s of the staple, as will be understood from an examination of Figs. 2, 3, and 4. The bottoms of the recesses c 0 are for obvious reasons formed in a curved or arch shape to force the ends of the staple to take the configuration desired in the formation of the tie. The die member C is also provided with an elongated slot 0 to permit the introduction of the staple, as shown in Figs. 1 and 1, and this slot intersects both the wire-recess 0 and the tie forming recesses c a. The longer diameter of the slot 0 is disposed at an angle of about forty-five degrees to the wire-recess c and is disposed substantially perpendicularly to the recesses c 0', and the center of the slot 0 coincides with the center of the wire-recess 0.

In operation the crossed wires A and B are laid in position upon the lower die member, the upper wire B lying in line with the wirerecess (Z. Theupper die is superimposed upon the lower die member by hand or by any desired means, and the lower wire is held in line with the wire-recess 0. It is to be noted that each die member is provided with a Wire-recess for one wire only and that the portions of the opposing die which engage the wire are flat faces, being the inner plane face of the die. The die members may be provided with suitable devices (not shown) tohold them in registration, if desired. It will also be noted that the lower wire A as it engages the plane face of the lower die member crosses the central transversely-disposed recess d, as shown in Fig. 3. A tie-forming staple S is now inserted in the slot 0 as shown in Fig. 1, and driven home by any suitable means, such as a plunger E, as indicated in Fig. 1. As the staple is forced in the die members are pressed together, (or these operations may take place at differentinstants of time, if preferred.) The staple ends or legs will he forced by the tieforming recesses (Z 01 to coil around the lower wire A in opposite directions, as indicated in Fig. 8, and the ends of the staple as they bend upwardly will enter the tie-forming recesses c 0 and be bent over and across the intersection of the wires A B beneath the bend of the staple, the pressure or blow being sufficient to force the bend of the staple upon the ends of the same, as shown in the completed tie, Figs. 2 and 9. The pressing together of the die members will force the portions of the upper wire on each side of the tie into the lower wire-recess d and will force the intersecting part of the lower wire into the central transverse recess d, the effect of this action being to oppositely kink the wires A and B, as indicated in Fig. 10, so as to interlock the same. As the tie is formed tightly around these inheld in the die, the other die member being terlocked portions of the wires A and B, the wires cannot after the formation of the tie move longitudinally one with respect to the other, as will be readily understood.

What we claim, and desire to secure by Letters Patent, is-

1. A die for the purpose set forth comprising two die members each provided with a single wire-holding recess disposed at an angle to the wire-holding recess of the other die member, one of said die members being provided with tie-forming recesses to engage the ends of the tie-blank and bend them in opposite directions around one of the intersecting wires provided with tie-forming recesses adapted to bend the ends of the tie-blank beneath the central portion of the same, and having a slot for the insertion of the tie-blank, substantially as described.

2. A die for the purpose set forth comprising two die members each provided with a sin gle wire-holding recess disposed at an angle to the wire-holding recess of the other die member, one of said die members being provided with tie-forming recesses disposed substantially perpendicularly to one of said wirerecesses and parallel to each other and the other die member being provided with parallel tie-forming, recesses disposed angularly to the first-mentioned recesses and substantially perpendicularly to the central portion of the tieblank, and being also provided with a slot for the introduction of the tie-blank, substantially as described.

3. In a die for the purpose set forth, the combination with a die member having a flat face provided with a single wire holding groove or recess, having its end portions of greater depth than its central portion, a trans verse recess adjacent to the central portion of the wire-groove and tie-forming recesses on opposite sides of the wire recess substantially parallel to each other and to the wiregroove, of a second die member having a flat face provided with a single wire holding groove or recess and parallel tie-forming recesses intersecting said wire-holding groove and disposed angularly thereto, said second die member having a slot for the introduction of the tie-blank, substantially as described.

4:. In a die for the purpose set forth, the combination with a die member having a flat face provided with a single wire holding groove or recess having its end portions of greater depth than its central portion, a transverse recess adjacent to the central portion of the wire-groove, tie-forming recesses on opposite sides of the wire-recess substantially parallel to each other and to the wire-groove, I and recesses on opposite sides of the wiregroove to receive the ends of the tie-blank when the tie is completed, of a seconddie momber provided with a flat face, having'a single wire-holding groove or recess, diagonally-dis I member being provided with parallel tieforming recesses disposed at an angle to the tie-forming recesses of the other member for bending the ends of the tie-blank beneath the central portion or bend thereof as the tie is formed, substantially as described.

In testimony whereof we affix our signatures in the presence of two witnesses.
